气球法测环境氡浓度

Balloon-based Measurement of Environmental Radon Concentrations

氡浓度测量是放射性环境监测中的一项常规工作,测量方法有多种,多数方法因操作繁琐、测量时间长、受电源控制或装置的体积较大等原因,在实际工作中使用受到限制,而气球法测环境氡浓度操作简便、快速,较适合于现场工作。本文介绍采用气球法结合FD-3005低本底α探测仪测环境氡浓度的基本原理和测量程序,并通过与双滤膜法从测量的灵敏度、精度等方面进行比较,验证该方法在实际工作中的可行性。

The measurement of radon concentrations is a routine work in environmental radioactivitiy monitoring, with a wide range of measuring methods. Due to inconvenient operation, long time consumed and large device volume, some of these are limited in use. Ballon method is fit for the measurement of environmental radon concentrations for its handy, rapid operation. In conjunction with the working principle of FD-3005 low background a dectector in regard to environmental radon concentration measurement, the paper aims to examine the feasibility of the balloon in practical measurement.
